[jira] [Commented] (CAMEL-5723) camel-jaxb: partClass and partNamespace dynamically set by header

["Claus Ibsen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-5723?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14623393#comment-14623393 ] 

Claus Ibsen commented on CAMEL-5723:
------------------------------------

You can use the data format component and use a "dynamic to". But yeah maybe also nicer to improve jaxb dataformat to support a header to control the behavior.

> The Camel JAXB Data Format allows to specify a partClass and partNamespace on the data format configuration. 
> If you have many cases of partial marshalling or unmarshalling, you're forced to configure as many data formats as part classes you'll ever need to handle.
> Aside from being inconvenient, it makes route initialisation pretty inefficient because a JAXBContext is created per data format, performing a full scan and reflection of the package each time. Slows down route startup considerably.
> Enhance the Camel JAXB Data Format so that it's capable of doing partial unmarshalling at runtime based on message headers.
